what dont you understand?

Double check all your work, maby you have left off something/dissconted.

For the coil packs and tps stuffing up, dont know. sounds weird.

I wouldnt think that messing around with the boost solenoid could hurt anything else.

The coil codes are probably from the overboost - ie to larger gap and the spark cannot ionise the gap. This is probably what is generating the coil missfire codes. Was there a forced shutdown code along with the TPS code?

mabee squirting half a can of wd40 into the vacume hose has fouled the plugs.

causeing the error code and going to limp mode with 4.5 psi boost.

Is your car stock?

If it is and it's pinging on factory tune, something in your fuel system could be f'ed.
